Jodi Arias was back in court Thursday for a status hearing on the penalty phase of her murder trial, this time donning black-and-white prison stripes instead of civilian clothing.

It was her first time in the Arizona court since May 22, when jurors failed to reach a unanimous decision on her sentence for killing her ex-boyfriend Travis Alexander. She was convicted of first-degree murder on May 8.

Because jurors in her murder trial were unable to agree on a sentence of life or death for Arias, trial attorneys must pick a new jury to decide her fate. The retrial was originally scheduled for July 18, but Arias' defense attorneys have asked the judge to delay the trial until January to give them more time to prepare.

The judge will wait to rule on their request and has kept the July 18 date on the calendar for another hearing on the matter.

Most of the discussion among attorneys on Thursday took place in the judge's chambers, off camera.

Arias was shackled and flanked by several heavily armed guards as she entered the courtroom.

The new jurors will deliberate Arias' sentence only. Arias' conviction for the grisly slaying of Alexander stands, as does the jury's finding that she carried out the crime in a "cruel manner."

If the new jury is unable to reach a unanimous decision on her penalty, Arias will automatically be sentenced to life in prison. The judge will then decide whether she will get life without parole or life with the eligibility of parole after 25 years.
